Thermal barrier coatings are frequently used to insulate elements of gas turbines and aero-engines that operate at high temperatures. Thermal Barrier Coatings, which are constructed of low thermal conductivity ceramics, can lower the surface temperature of a superalloy component by up to 300 K. The most popular material for thermal barrier coatings, yttria-stabilized zirconia (YSZ), resists thermal shock and fatigue.Metal parts used in both aero- and land-based gas turbines are frequently protected with thermal barrier coatings (TBCs).
A combustion chamber, blades, and vanes are among the parts of the hot-section. Heat transfer from the high temperature gas to the metal surface is significantly reduced as a result of TBC.
Components like gas turbines, aeroengine parts, etc. are insulated using thermal barrier coatings. These are employed in the aerospace industry as well as stationary power plants. The adoption of Thermal Barrier Coatings over the predicted period is a result of the growing vapour deposition technology. HVOF painting is a precise thermal barrier coatings technique used to preserve or repair a product's surface. By increasing its abrasion and wear resistance and chemical prevention, this surface engineering approach increases equipment life.
